 Zusammenfassung: The evaluation of the effect of organic compounds and microorganisms in formation and precipitation of colloids using artificial brines was performed by TNO using selected organic compounds based on the analysis of sampled fluids corresponding to the information gathered on the sites by GFZ. The same was done with biofilms prepared with microorganisms (Thermaerobacter sp., Penicilium citrinum) isolated from geothermal stations by UNINE. All carboxylic acids tested had an inhibiting effect on the precipitation of calcium carbonate. The biofilm components seem to develop intense interaction with the ions, nuclei and/or crystals formed during the executed experiments. In the presence of biofilms, the transformation of the intrinsically formed vaterite morphology to equilibrium calcite morphologies is delayed or hindered and scaling was inhibited.
